Specification forming part of Letters Patent No. 44, I 70, datedSeptember 13, I864.

To all whom it may concern:

Be it known that I, ALFRED EDWARDS, of Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inRadiating Heat-Regulators; and I do hereby declare that the following isa full, clear, and exact description of the same, reference being had tothe accompanying (riwfngs and letters of reference marked thereon, whichform a part of this specification, and in which Figure 1 represents avertical central sectional view of my invention; Fig. 2, a transversesectional view at the red line 00 in Fig. 1, and Fig. 3 a transversesectional view at the red line 3 The nature of my invention consists inthe use of a chamber containing a metallic plate, arranged as hereafterdescribed, constructed in the stovepipe for the purpose of regulatin gthe heat of the stove.

To enable those skilled in the art to manufacture and use my invention,I will proceed to describe the same with particularity.

The same letters of reference refer to the corresponding parts in thedifferent figures.

A represents the ordinary stovepipe, and B ihe chamber, which is eitherconstructed in the pipe or constructed separately and put into the pipe,forming a part of the pipe, as shown. In the said chamber B there is aplate. G, which is supported by the rod D. The plate (7 is arrangedwithin the said chamber so as to be directly over the pipe A, and theannular space around said plate between it and the wall of the chamberis equal to the space in the pipe A. The plate 0 is arrangedhorizontally or at right angles to the walls of the chamber, and may befixed rigidly, or it may be so arranged that it can be turned for thepurpose of removing the soot and cinders that might lodge upon it. Thechamber B may be constructed of any desired relative size to the pipe A;but whatever its size is the size of the plate 0 is varied accordingly,so that the area of the annular space between the plate and the walls ofthe chamber shall be equal to the area of the space in the pipe A. Bythis arrangement the heat of the stove passing up the pipe A strikes theplate 0 and is radiated, and at the same time, on account of the annularspace around the plate 0 being equal to the capacity of the pipe A,thedraft of the stove is not checked.

E is a common damper put in the pipe A for the purpose of regulating thedraft of the stove; and F is the handle by which the said damper isturned. The said damper E may be put into the pipe A either above orbelow the chamber B.

In all ordinary heat-regulators whenever the heat is in any way checkedor radiated, the draft of the stove is also checked, and the result isthat the stove smokes and is apt to become clogged, and not unfrequentlythe regulators are thrown awayas useless.

I do not confine myself to putting the plate G at any particular part ofthe chamber, neither do 1 limit myself to any particular form ofchamber.

Having thus fully described the construction and operation of myinvention, what I claim, and desire to secure by Letters Patent, 1s

1. The chamber B, provided with the plate 0, when arranged in the pipeA, substantially as and for the purposes set forth.

' 2. The combination and arrangement of the chamber B, the plate 0, thepipe A, and damper E, constructed and operating sub stantially as andfor the purposes herein described.
